Most Linux users know vim as a text editor that descended from vi. It can also function as a tool for encrypting text files. In this post, we examine how this is done and how to reverse the process.

Carefully, using these modulus & remainder for getting a new method for encrypting and decrypting the message. Though complex encryption techniques have been employed in safeguarding data.

With this, either exactly the same function does encryption and decryption, or one function does encryption and a similar, but different one does decryption. The most popular algorithm is called AES.

Encryption-decryption is one of those techniques which are quite popular. But, the complexity which is involved in this technique doesn’t allow its users to apply it in a simpler way.
